Incretin-based pharmacotherapy: from physiological mechanisms to management of type 2 diabetes and obesity

E.V. Khaikina, Sergei N. Kozlov, A.I. Zaleskaya

Positive effects of incretins on glucose metabolism was a basis for development of the new class of drugs with incretin activity. Currently, incretin-based pharmacotherapy is becoming the main approach for the treatment of type 2 diabetes mellitus and obesity. Its important advantages …

On the Mechanisms of Heterogeneous Recombination of Nitrogen and Oxygen Atoms

Sergei N. Kozlov, Boris Evgen'evich Zhestkov

Abstract The problem of the heterogeneous recombination of nitrogen and oxygen atoms is considered. The processes influencing the results of measurements of the recombination probability are analyzed. This study presents the authors' data on the heterogeneous recombination of atoms in the temperature …

Dynamic metastable vortex states in interacting vortex lines

Sergei N. Kozlov, Jérôme Lesueur, Dimitri Roditchev, C. Feuillet-Palma

Abstract The electron transport in current-biased superconducting nano-bridges is determined by the motion of the quantum vortex confined in the internal disorder landscape. Here we consider theoretically a simple case of a single or two neighbouring linear defects crossing a nano-bridge. The …

Comportement critique des nanofils supraconducteurs

Sergei N. Kozlov

Les détecteurs de photons uniques basés sur des nanofils supraconducteurs à basse température ont déjà démontré d'excellentes propriétés et des performances remarquables dans diverses applications en dessous de 1K, allant de l'information quantique au test de circuits intégrés. Dans ce contexte, l'idée …

Scalable nanofabrication of high-quality YBa 2 Cu 3 O 7−δ nanowires for single-photon detectors

P. Amari, Sergei N. Kozlov, Eliana Recoba Pawlowski, Z. Velluire-Pellat et autres

The realization of superconducting single-photon detectors operating above the liquid-helium temperature is currently the focus of intense research efforts. Here, we present the fabrication of ultraclean encapsulated nanowires from commercially available thin films of $\mathrm{YBa}$${}_{2}$$\mathrm{Cu}$${}_{3}$$\mathrm{O}$${}_{7\ensuremath{-}\ensuremath{\delta}}$ by high-energy oxygen-ion irradiation. The structured nanowires, …

Anomalous microwave response in the dissipative regime of topological superconducting devices based on Bi2Te2.3Se0.7

Vasily S. Stolyarov, Sergei N. Kozlov, Dmitry S. Yakovlev, N. Bergeal et autres

Superconducting proximity junctions based on topological insulators are widely believed to harbor Majorana-like bound states. The latter serves as a paradigm non-local topological quantum computation protocols. Nowadays, a search for topological phases in different materials, perspective for a realization of topological qubits, …

Hybrid quantum systems with high-T$$_c$$ superconducting resonators

Z. Velluire-Pellat, É. Maréchal, N. Moulonguet, Guilhem Saïz et autres

Superconducting microwave resonators are crucial elements of microwave circuits, offering a wide range of potential applications in modern science and technology. While conventional low-T[Formula: see text] superconductors are mainly employed, high-T[Formula: see text] cuprates could offer enhanced temperature and magnetic field operating …

The electron transport in current-biased superconducting nano-bridges is determined by the motion of the quantum vortex confined in the internal disorder landscape. Here we consider a simple case of a single or two neighbouring linear defects crossing a nano-bridge. The strong anharmonicity …

Effect of the Composition of a Gas Mixture on Determining the Probability of Heterogeneous Recombination of H, O, and N Atoms on Quartz

Sergei N. Kozlov, Boris Evgen'evich Zhestkov

Abstract Experimental studies of the processes of the heterogeneous recombination of H, O, and N atoms on quartz at reactor pressures close to atmospheric atmosphere at altitudes of 60 to 70 km are carried out. An experimental setup for determining the effective …

Revealing Intrinsic Superconductivity of the Nb/BiSbTe2Se Interface

Andrei Kudriashov, Ian Babich, Razmik A. Hovhannisyan, Andrey Yu. Shishkin et autres

Abstract Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top of a topological insulator (TI) surface. Here, the double critical current in the Josephson junctions based on the topological insulator is observed in the …

Vanishing Confinement Regime in Terahertz HgTe Nanocrystals Studied under Extreme Conditions of Temperature and Pressure

Stefano Pierini, Francesco Capitani, Michael R. Scimeca, Sergei N. Kozlov et autres

While HgTe nanocrystals (NCs) in the mid-infrared region have reached a high level of maturity, their far-infrared counterparts remain far less studied, raising the need for an in-depth investigation of the material before efficient device integration can be considered. Here, we explore …
